Meta Analysis
Efficacy of Pulsed Radiofrequency in Herpetic Neuralgia: A Meta-Analysis of Randomized Controlled Trials.
Herpes zoster and postherpetic neuralgia (PHN) are often refractory to current standard treatments and can reduce patients' quality of life (QoL). Pulsed radiofrequency (PRF) effectively controls intractable neurological pain. The aim of the study was to conduct a systematic review and meta-analysis to evaluate the efficacy of PRF in PHN management. ⋯ PRF safely and effectively reduced pain scores and improved QoL in patients with herpes zoster in the cervical to lumbosacral areas. PRF could be considered during refractory PHN treatment. Future studies require standardized PRF settings and outcome assessment tools, including physical and emotional function assessments.

Multicenter Study Clinical Trial
10 kHz SCS for chronic postsurgical pain: Results from a 12-month prospective, multicenter study.
Chronic postsurgical pain (CPSP) can be caused by peripheral nerve injury (PNI) resulting from surgical procedures and has a significant neuropathic component. This prospective, single-arm study was conducted to document the effectiveness of 10-kHz spinal cord stimulation (10-kHz SCS) as a treatment for patients with CPSP. ⋯ 10-kHz SCS is effective and tolerated in patients with CPSP, and further study of its clinical application in this population is warranted.

Responses of spinal progenitors to spinal cord stimulation (SCS) following spinal cord injury (SCI) in rats were assessed to reveal their potential contribution to SCS-induced analgesia. ⋯ Spinal progenitor cells appear to be activated by SCS via descending pathways, which may be enhanced by gabapentin and potentially contributes to relief of SCI-induced neuropathic pain.

Pocket pain, does location matter: a single-centre retrospective study of patients implanted with a spinal cord stimulator.
Spinal cord stimulation (SCS) is an effective therapy for alleviating pain but reported complication rates vary between healthcare centers. This study explored the prevalence of pain associated with Implantable Pulse Generators (IPGs), the component that powers the SCS system. ⋯ These findings suggest that IPG site pain is a common complication, contributing to SCS revisions and explantation. This study shows that anatomical factors and baseline characteristics of individual patients may contribute to IPG site pain and indicates that exploration of potential factors leading to IPG revision is required.

Randomized Controlled Trial
High Frequency (HF10) Spinal Cord Stimulation for Chronic Neuropathic Pain.
Spinal cord stimulation (SCS) is well established treatment. In a prospective randomised controlled trial, novel 10-kHz High-frequency Therapy (HF10 Therapy) was superior to traditional low-frequency SCS for the treatment of chronic back and leg pain. ⋯ The patient reported 90% pain reduction at follow-up. Thoracic HF10 SCS is effective modality in managing chronic neuropathic pain.
